An Apostille, in full "Apostille certification," is an international authentication that confirms the signature and seal on a public document, performed by a designated government authority (usually the Ministry of Foreign Affairs or the Supreme Court). It does not certify the authenticity of the document's content but rather verifies the identity and authority of the person who issued it.
Before the Hague Convention, for a document to be legally effective in another country, it typically had to undergo a complex "dual authentication" process: notarization by a local notary, certification by the Ministry of Foreign Affairs, and finally, legalization by the embassy or consulate of the destination country. The Apostille simplifies this into a single certification step, significantly improving the efficiency of international civil and commercial interactions.
With the acceleration of globalization, the Apostille has become an indispensable part of cross-border legal practice. Whether for an individual dealing with overseas property or a company conducting a cross-border merger, an Apostille serves as a "passport" ensuring the document is recognized by foreign legal systems.
